West Indian manatees (Trichechus manatus) are listed as vulnerable (IUCN Red List, 7 March 2009; Deutsch et al., 2008), with the subspecies Trichechus manatus latirostris and T. m. manatus (Florida and Antillean, respectively) considered endangered (IUCN Red List, 21 January 2011; Deutsch, 2008; Self-Sullivan & Mignucci-Giannoni, 2008). Manatees are not native to The Bahamas; however...

The cedar glades and barrens of the Inner Central Basin (ICB) of middle Tennessee support a unique and diverse flora and fauna and represent some of the state's most valued natural areas. We conducted herpetofaunal inventories of the cedar glades, associated barrens, cedar-hardwood forest, and adjacent aquatic habitats of the Stones River drainage of Middle Tennessee, focusing our...

Coastal vulnerability assessments tend to focus mainly on climate change and especially on sea-level rise. Assessment of the influence of nonclimatic environmental change or socioeconomic change is less well developed and these drivers are often completely ignored. Given that the most profound coastal changes of the twentieth century due to nonclimate drivers are likely to continue...

Habitat stability of coastal ecosystems, such as marshes and mangroves, depends on maintenance of soil elevations relative to sea level. Many such systems are characterized by limited mineral sedimentation and/or rapid subsidence and are consequently dependent upon accumulation of organic matter to maintain elevations. However, little field information exists regarding the contribution...

Okaloosa darters (Etheostoma okaloosae) are small fish found only in a few streams in the Florida panhandle. This species has been listed since 1973 as endangered due to habitat alteration resulting from erosion, the potential competition from brown darters (E. edwini), and a limited geographic distribution. In recent years, however, Okaloosa darters have benefited from improved resource

Albedo was monitored over a two-year period (beginning April 2008) at three forested wetland sites in Florida, USA using up- and down-ward facing pyranometers. Water level, above and below land surface, is the primary control on the temporal variability of daily albedo. Relatively low reflectivity of water accounts for the observed reductions in albedo with increased inundation of the...

Compensatory changes in juvenile survival allow fish stocks to maintain relatively constant recruitment across a wide range of stock sizes (and levels of fishing), but few studies have experimentally explored recruitment compensation in fish populations. We evaluated the potential for recruitment compensation in largemouth bass Micropterus salmoides by stocking six 0.4-ha hatchery ponds...

Nearly 14 years have passed since the first atlas, World Mangrove Atlas (Spalding et al. 1997), was published. While scientists throughout the world have shared their insights about these ecosystems from a handful of “classic” mangrove ecology treatises, no book since has provided the same platform for understanding the global importance of mangroves by simply defining their distribution...

Avian conservation efforts must account for changes in vegetation composition and structure associated with climate change. We modeled vegetation change and the probability of occurrence of birds to project changes in winter bird distributions associated with climate change and fire management in the northern Chihuahuan Desert (southwestern U.S.A.). We simulated vegetation change in a...
